sudo systemctl enable nvidia-suspend.service
sudo systemctl enable nvidia-hibernate.service
sudo systemctl enable nvidia-resume.service

I'm on Ubuntu 22.04, and after installing CUDA I was unable to suspend. The following steps worked for me:

• Inside /etc/systemd, delete all of the files that include nvidia and suspend or hibernate. There are three services inside /etc/systemd/system, which I deleted. There are also some other dead nvidia links inside systemd-hibernate.service.requires, systemd-suspend.service.requires, which I deleted.

I wish I knew the exact names of the files that I deleted, but since they're now gone, I can't remember their exact paths. But in a nutshell, go into /etc/systemd, and do find . -iname nv*, and then delete all the of the suspend, resume, and hibernate scripts.

DO NOT DELETE nvidia-powerd.service and nvidia-persistenced.service.

Once you're done with that, do systemctl daemon-reload.

This doesn't worked form me.
I removed all nvidia files you said. Indeed, if i do systemctl list-unit-files | grep nvidia it returns

nvidia-persistenced.service                                               enabled         enabled
nvidia-powerd.service                                                     enabled         enabled

and with find /etc/systemd -iname nv*

/etc/systemd/system/multi-user.target.wants/nvidia-persistenced.service
/etc/systemd/system/multi-user.target.wants/nvidia-powerd.service

but I'm still not able to resume the laptop.

My nvidia-smi is

@bmharper Your solution works perfectly for me (driver 515)!

Thanks @bmharper !!! Worked for me too, in the Nvidia On-Demand mode. I haven't tried other modes yet, but I'm fine with this one.

My story is: Linux Mint 20.3 Cinnamon, kernel 5.4.0-126. Recently installed CUDA toolkit, which updated my nvidia driver from 470 (if I'm not mistaken) to 515, which in turn had broken my auto-suspend on lid close. The Quit->Suspend button haven't worked either. Only way I could suspend is by running pm-suspend from terminal.

@bmharper That works for alienware laptop with nvidia driver 515

It works. The power drain I see before is not related to nvidia graphic card.

I tried to put the alienware laptop to airplane mode and pull out usb dondle before put into suspend, and put in the backpack for the whole night. The battery level only down by 9% which is normal, and no extra heat in the backpack.

BTW: I also update the driver to version 520, and upgrade ubuntu to 22.04.1 LTS. Works fine.

sudo rm /etc/systemd/system/systemd-hibernate.service.requires/nvidia-resume.service
sudo rm /etc/systemd/system/systemd-hibernate.service.requires/nvidia-hibernate.service
sudo rm /etc/systemd/system/systemd-suspend.service.requires/nvidia-resume.service
sudo rm /etc/systemd/system/systemd-suspend.service.requires/nvidia-suspend.service

worked for me. Thank you very much.

For me, with nvidia-driver-495, the simple solution was to remove the damaged symlinks from systemd. You most likely have them if you upgraded from nvidia-driver-470, because 470 still included the .service files in /lib/systemd/system/. The files are no longer included in 495 but the postinst script does not remove the symlinks. So, remove them with:

sudo rm /etc/systemd/system/systemd-hibernate.service.requires/nvidia-resume.service
sudo rm /etc/systemd/system/systemd-hibernate.service.requires/nvidia-hibernate.service
sudo rm /etc/systemd/system/systemd-suspend.service.requires/nvidia-resume.service
sudo rm /etc/systemd/system/systemd-suspend.service.requires/nvidia-suspend.service

Works instantly, no need of rebooting or logging off.

This does the job. Thank you.

sudo rm /etc/systemd/system/systemd-hibernate.service.requires/nvidia-resume.service
sudo rm /etc/systemd/system/systemd-hibernate.service.requires/nvidia-hibernate.service
sudo rm /etc/systemd/system/systemd-suspend.service.requires/nvidia-resume.service
sudo rm /etc/systemd/system/systemd-suspend.service.requires/nvidia-suspend.service

Thank you, This worked in my case.

The method works. In case you need fresh files install the services, you can get your driver version from NVIDIA. Use nvidia-smi to get the exact version and then run the .run file with --extract-only flag: sudo bash NVIDIA-Linux-x86_64-515.65.01.run --extract-only.

Then you run the given commands setting the TMPL_PATH to the path where you've extracted the files. Keep in mind that the files for this driver (515.65.01) have a slightly different locations as stated in the original post. So the updated commands should be like this:

TMPL_PATH=/home/user/Downloads/NVIDIA-Linux-x86_64-515.65.01/systemd

sudo install --mode 644 "${TMPL_PATH}/system/nvidia-suspend.service" /etc/systemd/system
sudo install --mode 644 "${TMPL_PATH}/system/nvidia-hibernate.service" /etc/systemd/system
sudo install --mode 644 "${TMPL_PATH}/system/nvidia-resume.service" /etc/systemd/system
sudo install "${TMPL_PATH}/system-sleep/nvidia" /lib/systemd/system-sleep
sudo install "${TMPL_PATH}/nvidia-sleep.sh" /usr/bin

sudo systemctl enable nvidia-suspend.service
sudo systemctl enable nvidia-hibernate.service
sudo systemctl enable nvidia-resume.service
